Be itknown that we, EMIL SALTZKORN and LUDWIG NICOLAI, subjects of theKing of Saxony, residing at Dresden, Saxony, in the German Empire, haveinvented a certain new and Improved Machine for Riveting Cardboard,Leather, 850., (for which we have obtained Letters Patent as follows: inGermany, No. 70,554, dated February 14, 1893 in Great Britain, No.3,418, dated February 15, 1893; in France, No. 228,063, dated February20, 1893; in Belgium, No. 103,576, dated February 22, 1893, and inAustria-Hungary, No.'10,100

and No. 25,576, dated July 5, 1893,) of which the following is aspecification.

--The object of this invention is to provide a machine by means of whicha great variety of materials-such as cardboard, leather, fab-v ric, andthe like-may be joined by metallic staples or rivets, the machine beingso constructed as to manufacture the metallic staples or rivets and feedthem to the riveting points as required The principal object of theinvention is to devise a machine which may be utilized in themanufacture of cardboard boxes for joining together the meeting edges ofthe sides or walls of such boxes, although it may be used for variousother purposes as wellsuch, for example, as the securing together of anumber of sheets of paper, cardboard, or other material, or for joiningtogether the edges or surfaces of plates, sheets, washers, bands, or

' other articles made ofsheet material of any kind.

Fig. 9 is asectional elevation on the line 6 6, Fig. 6, showing one of the stapleor rivet dies. Figs. 10, 11, 12, and 13 are views illustrating insimilar manner the different positions assumed by the dieblock atdifferent stages of its travel. Fig... 14 is a transverse sectionalelevation on the line ff, Fig. 2, illustrating, on an enlarged scale,the construction of the feeding-rollers. Fig. 15. is an enlargedsectional elevation. on the line g g, Fig. 1. vation on the line h h,Fig. 15. Fig. 17 is a plan view of the parts illustrated in Fig. 16.Fig. 18 is a sectional elevation on the line 'ii, Fig. 1. Figs. 19 and19 show one of the staples or rivets before and after being bent up intoform. Figs. 20 and 20 are similar views of another form of rivet; andFigs. 21 and 22 represent the manner in which such rivets or staples areapplied at the corners of a'box, either directly at the angle formed bythe junctionof two walls or on thetwo adjoining sides or walls.

The operating'parts of the machine are supported upon a suitableframework 1 2, the portion 1 being provided with a series of bearings inwhich are supported two shafts 3 4, having their axes coincident andtheirabutting ends being provided,respectively, with clutching orcoupling disks 12 and 11, which may be thrown into or out of contact, asdejecting tongue 11*, extending beyond the periphery of the disk, and iscompelled torotate with the same by pins 11, projecting from the face ofthe disk. The disk 12 has pins 12, which engage with the ring 11 whenthe latter is moved toward said disk bythe action of the spring 11 inthe disk-11.

The clutching of the disks is governed by a pedal 13,.fulcrumed to theframe and normally held up, with the disks separated, by atension-spring 13. At. a point on the framework to'one side of the disksis a bracket 114, inthe upper portion of'which is formed a bearing for ashaft 115. On one end of this shaft is an arm 116, having its outer endconnected by a rod 14 to the pedal, and on the opposite end of saidshaft is an arm 117, having'on one Fig. 16 is a sectionalele' on darecess 118, adapted to receive the projectingtongue 11 as shown in Fig.17. The side of the recess 1'18 nearest the disk 12 has an inclined face119, which may act as a wedge to force the tongue 11 to the inoperativeposition shown.

In the operation of the machine the depression of the pedal 13 willcause the raising of the arm 117 and leave the tongue 11 free, so thatthe ring 11 may, under the action of the springs 11, be moved intocontact with the pins 12 of the disk, and so turn the shaft 4 and effectthe movement of the operating parts of the machine.

- To disconnect the shaft it is merely necessary to remove the pressureon the pedal, when the spring 13 will move it to the position shown inFig. 1, and the arm 117 will then fall with its. inclined face119.directly in the path of the tongue 11", and as the disk 11 rotatessaid tongue will engage on the inclined face and will be directed intothe recess 118, in

' which position the ring 11 will be out of engagement with the pins 12.

The necessary driving motion is imparted to a belt-wheel 5, mountedloosely upon the shaft 3 and provided with a pin 6, projecting laterallyfrom the face of the wheel and adapted to engage apawl 8, fulcrumed at 9to a projecting lug formed integral with a sleeve or hub 10, rigidlysecured to the shaft 3. The pawl 8 is movable in one direction only andis normally held up in such position as to be engaged by the pin 6 by aspring 7, and when the belt-Wheel is rotating in the direction indicatedby the arrow, Fig. 1, the contact of the pin 6 with the pawl will effecta corresponding rotative movement of the shaft 3. If by accident thebelt-wheel 5 be rotated in the opposite direction injury to theoperating mechanism is avoided, as the pin 6 will insuch event depressthe pawl 8 against the action of the spring 7 without rotating the shaft3. p

In suitable bearings at the front of the machine is mounted a shaft 49,carrying at its lower end a disk 50, in which are a number of dies61four in the present instance-each of precisely the same constructionand each removable, so that dies of different shape or size may besubstituted for the manufacture,

of different staples or rivets.

Each die 61 comprises a substantially rectangular block having acentralstaple-receiving chamber extending entirely through the block, and inwhich the staples or rivets are bent into form and retained in positionuntil the die has been traveled to the point where the staple is to bedriven into the material being acted upon. Projecting latterly from theopposite sides of each block 61 are pivotpins 65,-ad'apted one to asuitable opening formed in the body offthe disk and the other in aremovable plate 50*, secured to the periphery of the disk in such mannerthat it may be readily removed when access is to be had to thedie-block, or' the latter is to be repaired or replaced by one ofdifiierent size or shape. On one of the pivot-pins of each block issecured a gear or friction wheel 62, the teeth of which project somewhatabove the bottom of a groove 66, formed in andconcensite sides of eachdie-block 61 and serving to' normally retain the latter in properposition. On the hub of the disk 50 isloosely mounted a collar formingpart of a die-carriage 54, and

held in position by suitable nuts in such manner as not to interferewith the movement of the carriage during its travel. In the carriage issecured a die-block 154, of any suitable size, and having formed thereina female blank-forming die of a contour corresponding to the shape ofthe staple or rivet being manufactured, and the male cutting-die beingof corresponding shape and operated at predetermined intervals to cutfrom a strip of metal blanks for the manufacture of the various staplesor rivets as they are used by the machine.

The bottom of the female die is formed by a plate 175, which may beintegral with the carriage 5%, or separate, as shown. This plate 175 hasan opening 176 of the same diameter as the openings in the die-blocks61, and the staple-blank contained in the female die is forced throughsuch opening by the'formingdie and is received by the die-blocks 61,each block receiving one staple in its proper turn. At one side of thecarriage 54: is hinged a plate 57, having one of its edges curved inhook-like form and adapted to engage successively in radially-arrangedslots or grooves 59 in the upper surface of the disk 50, so that as thelatter is rotated it will carry with it the carriage 5t until such timeas the hooklike plate is disengaged from the slot 59. The

plate is normally held down in engagement with the radial slot by aspring 177.

The staple-carrying disk 50 receives a stepby-step movement through themedium of beveled gears'5l and 52, Figs. 1 and 5, the gear 51 beingsecured to the upper end of the shaft 49, and having eight teeth orgrooves, with which engage alternately two teeth provided atdiametrically-opposite points on the wheel 52, the latter being securedto and revolving with the shaft 4, so that four complete rotations ofthe shaft 1 are necessary to effect one complete rotation of the disk50. During the intervals between the successive partial rotations of thedisk 50 the latter is locked in position by means of a lever 60,fulcrumed at 160 to a fixed pin on a bracket 161,

blocks 63 and 64, carried by they 35 or body portion extending entirelyacrossthe projecting from the frame and having one of its arms 162adapted to engage in a series of notches 163, arranged at equidistantpoints on the periphery of the disk 50, and the lever being held inengagement with any one of such notches by means of a spring 164,secured to thebracket16l. The opposite arm 165 of the lever 60 has aninclined edge facing the booklike edge of the plate 57 and being onaradial line from the center of the disk, as is also the edgeof theplate 57.

, The operation of this portion of the mechanism is as follows: 'Withthe parts in the position illustrated in Figs.-1 and 6 the blankcutting-die 42 will first descend and cut from a sheet or strip of metala rivet or staple blank of a character dependent upon the contour of thefemale die 154 in the carriage 54, forcing the blank down into contactwith the plate 175, and with the blank still in position in the femaledie the disk 50 will be rotated oneeighth of a revolution by theengagement at the proper point of the wheels 51 and 52. The

hook-like plate 57 of the carriage 54 is at this time in engagement withone of the radial slots or grooves 59 in the disk 50 and is carried withthe disk as the latter rotates, the eighth part of a revolution beingsufficient to move the female die 154 of the carriage 54 and one of thedie-blocks 61 immediately beneath the forming-die 45; On the descent ofthe forming-die 45the blank is forced from the female die 154 into theopening in one ofthe blocks 61, the pointed ends of the staple or rivetbeing bent upwardly, Fig. 10,,and the central die-chamber, as shown.During this movement the disk has been locked in position by theengagement of the arm 162 of the le ver with one of the eight peripheralnotches 163 of the disk. v\Vhen, however, the wheels 51 and 52 are againengaged and the disk started on a further movement the lockingarm 162 ofthe lever 60 will be forced out of the notch, causing its opposite armto move toward the carriage 54, and the inclined face of this arm of thelever engaging with the hook-like edge of the plate 57 will lift thelatter outof engagement with the slot or groove 59 against the action ofthe plate-spring 177, which normally holds the plate in engagement withthe slot. The carriage is then free to move back to itsinitial positionfor the reception of another rivet or staple blank, and this movement isaccomplished by means of a, cam 15, to which is adapted anantifriction-roller 18, held on one end of a bell-crank lever 17,. .theopposite end of which is connected by a flexible cord or chain 19 to thecarriage 54,

the cam 15 being so timed as to effect the withdrawal of the carriageimmediately after the hooked edge of the plate 57 has been disengagedfrom the slot 59.

I The shaft4 is provided with a series of grooved cams 40,43, and 46,the cam 40 acting through an antifriction-roller 41 to effect themovementof the blank-cutting die 42, and the cam 43 acting through 'anantifriction-roller 44 to effect the movement of the staple-formin gdie-45. The cam 46 is located near the end of the shaft 4 and actsthrough an antifrictionroller 47 to efiect the vertical movement of theejector or driving-in stamp 48, the latter acting simultaneously withthe blank-cutting die 42and serving to force the formed rivet or staplefromits position in the chamber of the die-block 61 into the materialto'be acted upon,

the die-block 61 having previously rotated to the'extent of half arevolution by the engagement of its pinion 62 with the fixed rack-teethof the block 63,Fig.1 1, so that whenit reachesthe ejector 48 the rivetor staple will haveassumed a position (shown in Fig. 12) with its apointed ends extending in a downward direction. ,After the rivet orstaple has been ejected the continued rotative movement of the disk 50will bring the (lie-block under the block 64, and the fixed rack-teethof the latter, Fig. 13, engaging the teeth of the pinion 62, will rotatethe die-block until it assumes its initial position and is again readyto receive a second rivet or staple; or, if necessary, this further halfrotation of the.die block may be omitted, as both sides of the die-blockmay be made of preciselythe same construction, so that a rivet. orstaple may bedriven into its receiving-chamber from eitheriend.

Immediately below the disk 50 is a worka table 25, preferably detachablefrom the machine, so that thev tables of different size and shape may besubstituted for different classes of work. This table is provided on aline co incident with the center of the ejector48 with a verticalrec,ess,in which is guided an anvil 26, the lower or foot portion ofwhich is supported on a block 124, having an upper inclined face andforming part of or connected to a rod 24, one end of which is connectedtoa lever 23, fulcrumed at 22 to the frame and at its upper end'beingprovided with an antifriction-roller 21, adapted to a peripheral cam orgroove in a cam 20, secured to the shaft 4, the I cam being so timedthat as theejector descends the block 124 will be drawn backward anditsv upper inclined face will raise the anvil 26 and aid the ejector inbending down the pointed-ends of the staple or rivet.

The rivets or staples are formed from a strip of suitable metal, whichis fed in under the blank-cuttingdie 42 by two feed-rolls 134 135,mounted on shafts 34,35, adapted to suitable bearings in a frame 136,supported by a bracket 137, the bearings of the upper shaft 35 beingformed by the blocks 138,'adapted to guideways 139, and adjustable bymeans of screws 38 toward and from' the lower roll. The shafts 34 and 35are provided with intermeshing gear-wheels 36, so that both will ro-.

tate and positively feed the -strip,and after each operation of the,blank-cutting die ,42 these rolls rotate asufficient distance to feedthe strip to'an extent necessary for the manufacture of a single rivetor-stapleblank.

Motion is imparted to the shaft 34 by a cam Ico 27, through the mediumof a lever 29, fulcrumed at 28 to a bracket on a frame and provided withan antifriction -roller 129, adapted to the cam-groove, the opposite endof the lever being connected by a rod 30 to a lever 81, which latter hasa loose sleeve 139 surrounding the shaft 84: and carries a pawl32,adapted to engage the teeth of the ratchetwheel 135, secured to suchshaft, so that the .movements of the lever will act through the pawl andratchet-wheel to rotate the shaft and pull the punched strip away fromthe blank-cutting die, a single rotation of the shaft 4 being sufficientto manufacture a single staple or rivet and asingle rotation of the cambeing sufficient to feed the strip a sufficient distance to bring afresh portion of the strip beneath the blank-cutting die.

It is considered of course that certain unimportant changes may be madein the details of the machine herein described. Thus, for instance,another form of coupling may be used in place of the disk 11 and 12described, or the number of cams may be lesscried and their Workaccomplished by the remainder, or the apparatus, to guard against thereversal of direction of rotation of the apparatus, may be changed oreven omitted altogether without departing from the spirit of ourinvention.
